Add DeepL Translator (close #203)

[soimort]

Due to recurring requests (#203, #121, and some email buried in the snow).

Usage:

1. (One-time) Call trans with option -e deepl.
2. (Permanent) Add :engine "deepl" to the configuration file.

Example:

$ trans :en 'mi casa es su casa' -e deepl
mi casa es su casa

my home is your home

[ Español → English ]

    My house is your house.
    My home is your home.
    my house is your house

There seems to be an encoding problem with DeepL (at least on my Mac). It returns non-ASCII characters with their Unicode code point. Example:

$ trans -b -e deepl :de+fr+es 'Listen to me!'
H\u00f6r mir zu!
\u00c9coute-moi bien!
\u00a1Esc\u00fachame!

The replaced characters here are ö, É, ¡ and ú.

This is only with the deepl engine. google, bing and yandex are fine.

@tflo
This is an existing issue on macOS / *BSD, since non-GNU systems do not have anything equivalent to GNU printf that properly prints Unicode-escaped string to stdout.

Thanks for the info. Will try to find a workaround…

Well, here an – ugly – workaround, with a bit of Perl to convert the characters:

$ trans -b -e deepl :de+fr+es 'Listen to me!' | perl -Mopen=':std',':encoding(UTF-8)' -pe '$_ =~ s/\\u(.{4})/chr(hex($1))/eg;'
Hör mir zu!
Écoute-moi bien!
¡Escúchame!

Tested only on a few samples.

Should be fixed by 4536adc using bash.

Preface: Sorry I am noob.

I 'git pull' in my local 'translate-shell' directory for the newest files (to include DeepL) however in the command line "trans -S" deepl is not found. Could you steer me in a direction to solving this problem?

Isn’t this committed yet?

With DeepL and 0.9.6.6 I still get the hex code points in the output when I remove my perl after-treatment. The same with 0.9.6.6-git:c8107fe (installed via Homebrew --HEAD).

Seems broken again in 0.9.6.7 (via homebrew)
